Definition

Barium is a milky fluid that absorbs
x-rays. Barium is placed into the bowels through the rectum. This is called an enema. Barium coats the lining of the lower intestines. This makes that area easier to see on an x-ray.

Possible Complications

Complications are rare. Some may have an allergic reaction to the barium or latex tube used during the test. Talk to your doctor about any allergies you may have.

What to Expect

Prior to Test

Tell your doctor if you are allergic to latex or barium.

Your intestines must be empty before this test. Your doctor may ask you to:

Eat a clear liquid diet.

Take laxatives.

Use a warm water or over-the-counter enema.

Do not eat or drink anything after midnight.

Description of Test

A well-lubricated enema tube will be gently inserted into your rectum. You may be given an injection to relax the rectum. Barium will be inserted through the tube. A small balloon at the end of the tube will be inflated. This balloon keeps the barium inside. You will be moved several times to make sure the barium coats the walls of the colon and rectum. A small amount of air will be inserted through the tube. A series of x-rays will be taken. After this, the enema tube will be removed.

After Test

After the test, you:

Will be shown to the bathroom to pass the barium and may be given a laxative

May feel mild-to-moderate abdominal cramping and may need to wait before driving home
